  org.opengis.pt.PT_CoordinatePoint

All Implemented Interfaces:

Serializable, Cloneable

public class PT_CoordinatePoint
extends Object
implements Cloneable, Serializable

A position defined by a list of numbers. The ordinate values are indexed from 0 to (NumDim-1), where NumDim is the dimension of the coordinate system the coordinate point belongs in.

Method Detail

hashCode

public int hashCode()

Returns a hash value for this coordinate. This value need not remain consistent between different implementations of the same class.

Overrides:

hashCode in class Object

equals

public boolean equals(Object object)

Compares the specified object with this coordinate for equality.

Overrides:

equals in class Object

clone

public Object clone()

Returns a deep copy of this coordinate.

Overrides:

clone in class Object

toString

public String toString()

Returns a string representation of this coordinate. The returned string is implementation dependent. It is usually provided for debugging purposes only.

Overrides:

toString in class Object
